Power-driven water feeding valve for passenger train

Abstract

The invention discloses a power-driven water feeding valve for a passenger train. The power-driven water feeding valve comprises a valve body, a valve cover, a connecting nut, a connecting flange, a worm reducer, a valve rod, a motor and a spring; the valve cover is fixedly arranged above the valve body; the connecting nut is in screw joint with the interior of an opening in the top of the valve cover; the connecting flange is arranged above the valve cover; the worm reducer is fixedly arranged at the top of the connecting flange; a vertically-arranged valve rod is in screw joint with the interior of the connecting nut, and the bottom end of the valve rod penetrates the valve cover to be arranged above a water inlet of an inner cavity of the valve body; the top end of the valve rod penetrates a vertically-arranged output shaft hole of the worm reducer to be arranged above the worm reducer; a spanner is movably inserted in the top end of the valve rod in a split manner; and a shaft of the motor is inserted into a horizontally-arranged input shaft hole of the worm reducer. The power-driven water feeding valve has the beneficial effects that opening and closing motion is more rapid, water resource management is better strengthened, and waste is reduced; remote operation facilities the improvement of water feeding operation efficiency, and the labor strength of staff is reduced; and manual and automatic integrated design is adopted, so that safety production is better guaranteed.

Description

Technical field: [0001] The invention relates to a water supply valve for a railway passenger car, in particular to an electric water supply valve for a railway passenger car. Background technique: [0002] my country has a large land area and a dense railway network. Due to the long running distance of the train, the large number of passing stations, and the large number of passengers to be sent, the on-board water tank must be refilled many times in the middle of the journey to meet the transportation requirements. After the railway has undergone six major speed increases, the operating speed and road network structure have undergone great changes. In order to meet the needs of the development of railway passenger transportation, the railway transportation organization has gradually reduced the parking time of passenger cars after arriving at the station, which has brought great pressure on the design of water supply stations for passenger cars and the water supply work a...

Problems solved by technology

The former has low efficiency and high labor intensity; the latter has a high degree of automation, which can effectively reduce labor intensity and improve work efficiency, but there are still inaccurate control of the switch position of the valve, incomplete opening and lax closing.
